TROUBLESHOOTING FOR SA6300Z
A. The power cannot be turned on :
1. Check the power supply (Battery Adaptor).
I. Check if have any deform or dirty on the spring of battery.
2. Check the connection between M/B with the other board. ( refer Fig. 1 & 2 )
I.. Check the connection between M/B and ST/B.
II. Check the connection between M/B and P/B.
III. Check the connection between M/B and CCD FPC board.
IV. Check the connection between M/B and LCD.
3. Current = 0mA when power on. ( refer Fig. 1 )
I.. Check the fuse is open or not. ( F1 & F2 of P/B )
II. Check if have any deform & dirty & cold-solder on the spring of battery
4. Power LED is on, but LENS still doesn't work. ( refer Fig. 1 )
I. Check the connection between M/B and FPC of LENS.
II. Check the function of LENS is OK.
III. Check the circuit of U8 of M/B.
5. Current is active but still could not power on. ( refer Fig. 1 & 2 )
I.. Check the Y1 & Y2 is active or not.
II. Check the function of ASIC, DRAM & memory.
6. Check P/B . ( refer Fig. 2 )
I. Check the connection between M/B and P/B.
II. Check all output voltage of P/B and analysis if incorrect output voltage was found.
